The extension could not be activated, as it triggered a fatal error.

Hello, I’d like to activate the Cost Calculator Builder extension after downloading it, but unfortunately I’m getting an error message “The extension could not be activated, as it triggered a fatal error.”.

I’ve tried uninstalling and reinstalling the extension, but it still doesn’t work.

I’ve also installed another extension to see if it does the same thing, but no, I can’t get it to work.

And everything is up to date, whether it’s my extensions, my theme or WP.
